. 1 v This invention relates to improvements in wheeled tables fortransferring invalids.

The principal objects of this invention are:

First, to provide a simplified form of wheeled table or hospital carrierfor transporting invalids in which the table or invalid supportingportion is both vertically and angularly adjustable so as to tiltdownwardly and depress the side of a'bed for facilitating transfer ofthe invalid from the bed to the table.

Second, to provide an invalid carrier in which the tilting motion of thetable occurs about a pivot located adjacent to the base of the carrierand remote from the free edge of the table whereby a minimum amount ofmotion of the tilting mechanism results in a maximum amount of movementof the table.

Third, to provide an invalid carrier having a simplified form ofvertical adjusting mechanism for the table carried entirely on swingablymounted supports sothat the vertical position of the table can bechanged in any of the angularly adjusted positions Of the table.

Other objects and advantages relating to the details of my table will beapparent from a consideration of thefollowing description and claims.

The drawings of which there are two sheets illustrate a preferred formof the table on the carrier.

Fig. 1 is an elevational view from what may be considered the front sideof the carrier.

Fig. 2 is a perspective view of the end of the carrier, portions of theupright casings being broken away to illustrate the elevating mechanismand with the dotted lines indicating the tiltedposition of the table.

Fig. 3 is a fragmentary end elevational view partially broken away invertical section through the driving mechanism for tilting the table.

Fig. 4 is a fragmentary end elevational view of the coupling between thetable support and the table tilting shaft, the view being partiallybroken away to illustrate the operating connection.

Fig. 5 is a fragmentary horizontal cross-sectional view through one ofthe uprights of the is carried on the uprightsfl l for vertical andClaims. (Cl. 5 86) over a bump or obstruction at the same time 2 tiltingadjustment as will be described in greater detail. f

The base I consists of a generally U-shaped tubular member 5 having itsopen end facing the front of the carrier and having the caster wheels 2mounted on the underside thereof in any of several well-known methods.Attention is called to the fact that one of the wheels 2A islongitudinally offset from the other wheel 2 on the end of the base sothat both wheels will not pass when the table is moved longitudinally.This provides smoother rolling motion of the carrier as it passes overirregularities such as the entrance to elevators. It will further benoted that one of the wheels is provided with a lock 6 for locking thecaster in one position for easier steering of the carrier.

The end arms I of the tube 5 are provided with aligned-pivots 8 (seeFig. 2) located adjacent to the rear side of the base and projectinoutwardly from the ends thereof. The pivots B are secured to and supportthe L-shaped arms 9 with the lower branches of the arms projectingforwardly along side of the arms 1 of the base. ihe forward ends of thebranches 9 have the se mental racks l0 secured thereto for operativeengagement with pinions ll. The pinions II are fixedly secured to theends of a tilt shaft I2 and the shaft [2 is journaled in the end arms Iof the base. Straps I3 are secured to the end arms and positioned inoverlapping relation to the pinions II and racks Iii. Backing rollers Mare carried onstraps for holdingthe racksrin engagement with the pinionsH. The two piece drum-like decorative casing I5 is provided around thepinions and the ends of the racks.

The center of the tilt shaft [2 is provided with a driving gear I6fixedly secured to the shaft and a yoke I! which has its arm positionedon each side of the gear and apertured to rotatably pass the shaft [2.The base of the yoke I! is bifurcated as at [8 to receive the worm iiiin tangential driving engagement with the gear [6. The bifurcations ofthe yoke are bored coaxially with the worm to receive the lower end ofthe tilting crank 29 for driving the worm. The upper end of the tiltingcrank is braced and rotatably supported by the brace rods 22 and a knob23 is carried by the upper end of the crank.

The upright branches 24 of the L-shaped arms 9 are provided withlongitudinalracks 25 on their forward sides and are lapped along thedepending posts 25 which support the framework I Of h ta le. 3-; uur her ps 21. ec red. to: v;

with respect to the branches 24 of the L-shaped arms.

Intermediate of its ends the elevator shafti29 is provided with ahousing 3| which encloses a driving gear and pinion similar to themechanism shown in Fig. 3. An elevating crank 32 extends from thehousing 3| and has its upper end secured to the frame of the table 3.Thus rotation of the crank .32 will change the elevation 'of the tablewith respect to 'the'base regardless of the angular position of thetable.

Decorative rectangular metal sleeves 33 and 34 are secured respectivelyto the uprights 26 and upright branches 24 enclose the uprights and theelevating mechanism.

From the foregoing description it will be apparent that the forward sideof my table may .be pushed over the edge 'of a hospital bed with thefront side of the base rolling underneath the'bed. The table 3 can thenbe lowered into contact with the bed and the front edge of the tablethen tilted forwardly and downwardly to depress the mattress and springssothat the table and bed form a trough for facilitating sliding orrolling the patient onto the table. After the patient is placed on thetable, the'table' can be raised to horizontal position and the entirecarrier pushed to a new position. In removing thepatient from the tableto another bed or operating table the reverse process can obviously becarried out.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:
